A major faux pas occurred at the world cup opening ceremony, which took place yesterday. When Nigeria was called, Niger’s flag was displayed, Huffington Post reports.

Some viewers commented on the incident via twitter:

The Nigeria Football Federation says it bears no grudge against FIFA or the 2014 World Cup Local Organising Committee for the error, Punch reports.

“If they called Nigeria and they raised Niger’s flag, it’s not a matter I can address from here. People that were there saw it and I know they will talk to FIFA about it. LOC and FIFA made an honest mistake.

I know they (FIFA and the 2014 World Cup LOC) will apologise for their mistakes and that should be the end of the matter,” said Musa Amadu, Secretary-General of the NFF.
